Mechanical Design Project Manager / Member

EMPOWER - LLEAP | San Luis Obispo, CA | 09/2019 - 12/2023

  • Club Purpose: To design a fully-assistive lower-limb exoskeleton for user(s) suffering from paraplegia.
  • Collaborated with other leads to lead new members, organize teams in club, and ensure all components integrable in full exoskeleton.
  • Helped analyze stresses and loads on knee during walking and sit-to-stand motion to design knee joint of exoskeleton and utilized Solidworks CAD to model design.
  • Manufactured prototypes of knee joint through 3D-printing and shop-based tools (aluminum model).
  • Worked as go-between for prototyping and mechatronics.
  • Completed a biomechanically accurate model of knee joint (senior project) and assisted in club as a member.

Senior Project - Biomechanically Accurate Exoskeleton Knee Joint

Senior Project | San Luis Obispo, CA | 09/2022 - 06/2023

  • Purpose: To design a biomechanically accurate knee joint for the lower limb exoskeleton being developed in LLEAP.
  • Was required to mimic the natural motion of the human knee, support the full expected load of one leg during sit-to-stand motion and walking, and be lightweight and integrable in the full exoskeleton.
  • Design: Created a four-bar linkage using link measurements from research to mimic natural knee movement and utilized a linear actuator to actuate joint.
  • Controls: Used an ESP32 and angular potentiometer to track the angular position of the knee and control its movement.
  • Code: Using C++ and OOP in Arduino, the angle of knee was able to be controlled through angle specification or bluetooth controls.
  • Worked through full engineering design process (Define Problem, Conduct Research, Brainstorm, Prototype, etc.).
  • Conducted analysis on numerous prototypes (through hand calcs and FEA).

Engineering Design Intern

Walters & Wolf Curtain Wall | Mukilteo, WA | 06/2020 - 04/2021

  • Designed and analyzed engineering drawings, models, and assemblies for curtain wall units.
  • Developed/adapted Inventor Professional and Vault Professional to meet company specific needs in order to improve efficiency and modeling standardization.
  • Facilitated transition from current modeling process (AutoCAD) to 3D-based modeling (Inventor-Vault-Fusion Team system); created and presented multiple presentations and led a class on Inventor modeling use

BR&D IRC Engineering Intern

The Boeing Company | Everett, WA | 06/2018 - 08/2018

  • Designed new system for testing 777X carpet; utilized MCC (Microscale Calorimetry Combustion) testing to measure combustibility of various materials that make up interior of 777X planes.
  • Managed, recorded, and quantified experimentally produced data on variety of materials; increased accuracy of tests and user-friendliness
  • Communicated/coordinated between multiple divisions within Boeing.
